Overview
The frequency response test measures the EMI receiver’s amplitude error as a
function of the tuned frequency. Measurements are made ranging from 50 MHz
to the maximum frequency range of the receiver under test. The signal source
amplitude is measured with a power meter to eliminate error due to source
flatness. The measured value is normalized to 50 MHz.
This measurement is performed for both RF inputs.
